WTF! My car is here

[rsiwicki]

maybe Greg can hook you up on the rotors or pads???? as his complete Q45 kit costs about $550 for all 4 pads/rotors/SS lines/ etc that are crossed drilled and slotted

[1992Q45A]

it already has the skyline brake system on it!

Just need replacement pads/rotors...

oh and the rear calipers are apparently hosed.

As for clearence.. The calipers clear the 16s, but BARELY..

It's in it's original form, like it came from stillen.. Has the OG AZEV wheels back on it...

[AZhitman]

Ah - I see. I was under the impression that there was NO WAY to fit 12.8" rotors in a 16" wheel... But as you said, it's snug.

[HeavyDuty]

Maybe I could trade you some brake stuff for the grill.

[1992Q45A]

12.8??????

[AZhitman]

Ooops - EDIT - Never mind, i just looked at the link...

That setup uses stock diameter rotors with bigger calipers.

I thought you were gonna go with the BIG rotors as well as the better calipers....

I'll go back to sleep now.

[1992Q45A]

Found out some interesting info

The Skyline GT brake system is dimensionally identical to the GT-R system excpet that the brake rotors are not cross-drilled. With the front rotors being less expensive and not need to purchase rear rotors, this is a great brake upgrade at considerable savings

Anyway, calipers are expensive. Do you guys think I could just order this caliper repair kit, and have them repaired?

Caliper repair kit consists of caliper rebuild kit and replacement caliper piston. For both items it's $50, instead of $350 for each caliper...

I don't know what goes into caliper repair vs replacement, any info would be great.

The Skyline GT-R (R-32) brake system will improve the braking performance of the 300ZX (Z32) by increasing the brake pad swept area by 6.8% and internal cooling capacity by 82% over the OE front brakes. see note below The light weight 6 1/2 lb aluminum front calipers are designed to clear the larger uni-directional rotors which in addition to being cross-drilled are 295mm (vs 280mm) in diameter and have a width of 32mm (vs 30mm).

Hitman, I don't think the rotors are that large.. I think the size has been mentioned in some previous posts.. I think they are like 11.5

I think the main difference is the rotor thickness and internel venting.. I know they came standard on the anniversary edition ZX.. seems like a popular upgrade for the Zs..

[1992Q45A]

According to mechanic guy they can be repaired.

Thank god, that saves me mucho dinero

[1qckser]

Ryan, is your setup somethin like this?

http://cgi.ebay.com/ebaymotors...sting

[AZhitman]

I was thinking of the R-34 kit (or the one I just ordered) which increades rotor diameter to nearly 13" (increasing swept area by 22%) and cooling capacity by 82% (due to venting and increased thickness). Add to that the increased clamping force of a 4-pot aluminum caliper and woo hoo!

So your car already either has a brake caliper relocation bracket, which provides the extra 15/2 = 7.5 mm clearance (or is this made up by using the different calipers)?

Thickness and venting IS indeed the difference.

Brake stuff is confusing.

[AZhitman]

That Yahoo auction is overpriced. Basically, those are 300ZX tt calipers and rotors, and there's NO reason they should cost that much USED (and JDM is no excuse).

I like how the tape measure is off by 3/4" on one picture...

[1992Q45A]

Hitman, the R34 GTR brakes have larger rotors.. beefy indeed

Nice upgrade, I didn't know you went down this route.. Did I just get some new info out of you

This is what I have

R32 GTR brake upgrade

Skyline rotors & calipers (stage 4). For those of you who have upgraded the horsepower capabilities on your 300ZX, better brakes take on an even more important role. Being able to stop a powerful (and somewhat heavy) car repeatedly from high speed, requires a larger braking system than what comes stock on the 300X. The Skyline kit you see here features (larger-size) front and (same-size) rear rotors that are cross-drilled and axially-vented. They are thicker and more durable than the stock rotors. Also included in the kit are bolt-on larger front calipers and their hanging pins. This is a superb choice for increased stopping power while fitting within the stock 16: wheels (you may also use larger wheels too).

They are 4 piston fronts and 2 piston rears

[1992Q45A]

Hitman,

Do you think the larger R34 GTR Brembos would work with the brackets I have for the R32 GTR brakes?

[AZhitman]

Not a chance.

Gotta relocate those calipers WAY out there to clear those pie pans...

This project is (like all good things) gonna take awhile.

p.s. You'll recognize my rotors when you see them - Here's a hint: NON-NISSAN, 323mm.

Supra rotors? I dont have time to look it up but thats my guess

[AZhitman]

[1992Q45A]

Oh man... I loved my supras brakes... They were so friggin awesome

Hey guys, I need your opinions

I can save roughly 40 per rotor by getting the GT rotors, vs the GTR rotors. The only difference is the GTR rotors are cross drilled.

I'm not thinking cross drilling is worth 40 dollars.. opinions?

[1992Q45A]

HITMAN!

If you are scheeming supra brakes, please count me in as your first customer. The MKIV had SOLID OEM brakes.. It's what lexus uses for their big braking now...

Porsche TT stoping distances, at toyota prices..

Everything on that was so damn over engineered... Man I loved it. Argh I'm depressed now.

[AZhitman]

I won't sell 'em. Too many projects going.

I'm cheap, so I'm piecing together something... Gonna see if I can replicate the Baer/Wilwood combo for under $400.

Cross-drilling is not worth $40. I'd rather have the extra material. Slotting would be nice, and worth $40 IMO...

Do you know the exact dimensions of those rotors? Wonder if there's something in the SP catalog, might be able to save you some coin.

p.s. You don't know how nice it is to hear you're being "fiscally conservative".

[1992Q45A]

The GTR brake system only includes the fronts.. The rears retain the OE spec of the ZX braking system.

Here is what I got

GT front rotorsHawk pads front/rearcaliper rebuild kit x2

$384.00 + shipping

I still need to do something with the rears... since the skylines the OE spec, I could just order 300zx rear rotors?

Heavy: emailed

[AZhitman]

Much better.

300ZX rear rotors would be smart.

[AZhitman]

<--- Chopped liver?

[1992Q45A]

Gotcha

[MiniMan]

Greg, if you're going with near 13" rotors up front, why wouldn't you just swap the Qs front calipers to the rear, buy rotors and make brackets?

Corey

[AZhitman]

Don't wanna MAKE the brackets - I'd rather buy them...

They're for a different application, but should be perfect for the Q.

[1992Q45A]

Please share what other application?

[1992Q45A]

Interesting article I found on a Z32 site. Comparison between R32 GTR and ZX brakes

quoting

"Comparison between the stock Z32 brakes (L) and the Skyline GT-R32 brakes (R)As you can see quite clearly the discs of the GTR32 are larger and thicker "



"and the difference between the calipers, Z32 (left) = aluminum, GTR32 (right) = iron"



I wasn't aware the skyline calipers were Iron, is this still the case?

[AZhitman]

Please share what other application?

3000GT VR-4.

BTW, that second pic doesn't show the calipers, but it DOES show the increased venting and rotor thickness.

The Skyline calipers are indeed iron.

Heavy suckers, and those rotors add a LOT of rotating mass... It's a catch-22.

[1qckser]

AZ how much do the 3000 rotors wieght compared to the Skyline setup? Ultimatley I guess its up to your driving style as to what brakes you want, I already have the 300ZX calipers, so coupled with some Hawk pads and a set of factory rotors, and stainless lines I should be ok as the only track my Q will see is the drag strip once.p.s Those Skyline rotors sure do look serious, wish I had the horsepower to turn em, coupled with 18s and those rotors I might see a best of a low 16 sec 1/4 mile.
